Abstract

Quantum-dot lasers are expected to attain remarkable reduction in threshold current and temperature-insensitive operation, however, high characteristic temperature of threshold current (T0) has not yet been achieved except lasers which required huge current injection. For example, the dot lasers with low threshold current density or currents close to 10 mA have T0of 40-80 K.
